Start a Game Functionality

[alexander-lee]

Go Changes:

• Move API Handlers to a subpackage called api_handlers to prevent circular dependency
• Added GetJSON function to Game struct
• Implement the Game Loop
• Start Game Loop on Post Request
• Fix API urls so that it works
• Move JSON Structs to separate file
• Player has a channel to receive messages from in order to input moves

What happens when a Game Starts:

• Game is created, players are randomly assigned
• Game's message handler is created
• For the Server's websocket handler, when a client registers, it checks if a game exists. If a game exists, a goroutine for the Game Loop is initiated

JS Changes:

• Add API Response helper (from whenisgreat)
• Update UI
• Message Handler updates the board to state from the websocket
